Various diseases can be cured or avoided from becoming serious if they are detected early. We have compiled a list of clues to help you detect diseases early and extend your healthy life span.

Diseases that are common causes of death among Japanese people


The cause of death among the Japanese is

1st: Cancer (30.4%).
2nd: Heart disease (15.8%)
3rd: Cerebrovascular disease (11.5%)
4th: Pneumonia (9.9%)
5th: Accident (3.4%)

This is the first time I’ve done this.

(Surveyed in 2007)

The number of people who suffer from lifestyle-related diseases such as diabetes and hypertension, which are risk factors for cancer, cerebrovascular and cardiovascular diseases, is on the rise in Japan these days.

Incidentally, lifestyle-related diseases include diabetes, hypertension, and obesity. Diabetes, for example, is a disease that is increasing due to the westernization of life compared to the past, and it can also be the cause of deadly diseases such as stroke and heart disease. All of these diseases are scary, but they are often caused by lifestyle factors such as drinking, smoking, diet, and exercise.

For each cancer

I would like to summarize the characteristics and early symptoms of each cancer from here.


Early symptoms
Stomach discomfort
Loss of appetite
Persistent nausea
Chest congestion
Black stools
Weight loss
Frequent burping

Some of these symptoms are actually specific to gastric cancer, but since they are common in daily life, most people leave them untreated without suspecting cancer.

5-year survival rate
Stage I: 87.8
Stage II: 62.0
Stage III: 40.5
Stage IV: 7.2

Gastric cancer is a curable disease if it is detected early. In other words, it is very important to detect it at an early stage. If you have any of the early symptoms listed above, we recommend that you have an examination.


Early symptoms
Persistent cough
Persistent chest pain
Shoulder pain
Feeling of pressure in the chest
Hoarseness (hoarse voice)
Weight loss
Enlarged finger ends and swollen cervical lymph nodes

Risk factors
The incidence of lung cancer is said to be 4.5 times higher in Japanese men and even 4.2 times higher in Japanese women than in people who do not smoke.

《The Brinkman Index》
For example, a 40-year-old who has smoked a pack of 20 cigarettes every day since the age of 20 would have 20 cigarettes x 20 years = 400. If this number exceeds 400, the risk of developing lung cancer increases, and if it exceeds 600, the risk of developing lung cancer becomes high.

Translated with (free version)

5-year survival rate
Stage I: 71.7
Stage II: 38.3
Stage III: 18.6
Stage IV: 4.3

Compared to other cancers, lung cancer has a very poor prognosis. However, if it is detected in Stage I, the survival rate is 71.7%, which means it is a cancer that should be detected early. If you have a persistent cough or shoulder pain, it is recommended that you have an early checkup without taking it too far.

colorectal cancer

Early symptoms.
Latent bleeding (occult blood is not visible to the naked eye.)
Change in defecation habits or nature of stool (shape, length, hardness, volume of stool)
Bloody stool
Abdominal pain
Abdominal mass of colon cancer
Rectal mass in rectal cancer
Low fever
Weight loss

5-year survival rate
Stage I: 98.7
Stage II: 85.3
Stage III: 76.2
Stage IV: 15.0

Colorectal cancer is famous for its high rate of metastasis. If metastasis (stage IV) occurs, the prognosis for life becomes worse at once. Therefore, early detection is very important.

prostate cancer

Frequent urination (especially nocturia)
Difficulty in urination
Residual urine feeling
Lower back pain
Paralysis of the lower half of the body

These symptoms occur in many older men with an enlarged prostate and they often neglect to go to the hospital.

Risk factors
High intake of fat
Vigorous sexual activity

5-year survival rate
Stage I: 89.0
Stage II: 85.6
Stage III: 83.9
Stage IV: 43.6

It is a cancer that has a good prognosis if detected in its early stage.

Prostate cancer is a cancer that can be cured in about 90% of people if it is treated early. However, prostate cancer is also very difficult to detect in its early stages. The reason for this is that there are no subjective symptoms specific to prostate cancer. If you notice any symptoms, it is necessary to have an early examination.

liver cancer

The largest number of people, nearly 60%, experience general malaise, followed by more than 40% who complain of loss of appetite, abdominal pain, and stomach upset.

Weight loss
Nausea and vomiting

However, there are many cases where these symptoms do not occur, and in more than 50% of patients, liver cancer is detected through imaging tests and other means while they are asymptomatic. In addition, the liver is known as the “silent organ” and it is difficult to show subjective symptoms even when abnormalities occur. In addition, general malaise and loss of appetite are symptoms that cannot be directly linked to cancer, so they are often mistaken for a simple cold or fatigue, and detection is often delayed.

Risk factors
Excessive alcohol consumption

5-year survival rate
Stage I: 49.8
Stage II: 37.7
Stage III: 17.7
Stage IV: 7.7

It is a cancer with a very poor life prognosis.
If you experience general malaise or loss of appetite, it is very important that you do not think that you are just tired, but have an examination.

breast cancer

Early symptoms
Lumps or dimples in the breast
Painful or hot breasts
Left and right nipples are misaligned
Nipples are sunken in
Redness, discoloration, or sores on the skin of the breast
Bleeding or discharge from the nipple
Lumps or swelling on the neck or under the armpits

Risk factors
Highly educated
Never married
Never been pregnant
Older age at first birth
Early menarche (less than 11 years old)
Menopause later than others (age 55 or older)
Have a family member with breast cancer

5-year survival rate
Stage I: 95.7
Stage II: 90.9
Stage III: 69.7
Stage IV: 32.2

Breast cancer has a very good prognosis if detected early.
If you have any symptoms, it is recommended that you have an examination.

cervical cancer

Cervical cancer is a disease that can occur in any woman who has had sexual intercourse, regardless of heredity or other factors.
Every year, 270,000 women around the world lose their precious lives to cervical cancer. In Japan, about 15,000 women are diagnosed every year. In Japan, about 15,000 people (including epithelial cancer) are diagnosed with cervical cancer every year.

Initial symptoms
No symptoms

Symptoms in advanced cases
Bleeding during intercourse
Abnormal discharge (increased brown or dark brown discharge, etc.)
Irregular bleeding (bleeding other than during menstruation)
Pain in the lower abdomen or lower back, etc.

5-year survival rate
Stage I: 90.4
Stage II: 70.1
Stage III: 49.4
Stage IV: 20.9

It is a cancer that has a relatively poor life prognosis when the stage is advanced. It is very important to detect it at an early stage.

cancer of the uterine body

Risk factors
High blood pressure
Those who did not get pregnant or had fewer pregnancies and deliveries
People who have had irregular menstruation for a long time

Early symptoms
Bleeding symptoms such as small amounts of bleeding and brown discharge often appear.

In this case, it is essential to ensure that the test is performed.

5-year survival rate
Stage I: 91.8
Stage II: 83.4
Stage III: 61.8
Stage IV: 22.6

The five-year survival rate for stage I uterine cancer is more than 90%, and that for stage II is more than 80%, which means that it is a cancer that can be completely cured if detected early and treatment is started.

heart disease

The scary thing about heart disease is that it can often take your life one day at a time. Death within 24 hours of the first symptoms is called “sudden death,” and more than half of sudden deaths that strike working-age people are due to heart problems. In this section, I would like to summarize ischemic heart disease, which accounts for the majority of cardiac deaths.

What is Ischemic Heart Disease?

Ischemic heart disease is a condition in which the coronary arteries that supply blood to the heart muscle become narrowed or blocked, and the heart muscle beyond these arteries is deprived of oxygen. Angina pectoris is when the coronary arteries become narrow and the heart muscle is temporarily deprived of oxygen, and myocardial infarction is when the coronary arteries become completely blocked.

1. Arteriosclerosis
The most common cause of ischemic heart disease is atherosclerosis of the coronary arteries. When caused by atherosclerosis, it is characterized by the fact that it often occurs during exertion.

2. Contraction
Angina and myocardial infarction are also caused by abnormal contraction of the coronary arteries. When caused by constriction, it occurs at rest and may be induced by smoking.

Risk factors
Three major risk factors

2. Other risk factors
Physical factors
Hyperlipidemia, obesity, diabetes, hyperuricemia, aging, heredity, menopause, arrhythmia

Lifestyle factors
Stress, lack of exercise, excessive drinking

1. Angina pectoris
A pressing pain in the anterior chest or a feeling of tightness in the chest that lasts for several to ten minutes. It is characterized by improvement with rest.

2. Myocardial infarction
Severe pain in the anterior chest that lasts for a long time. The face becomes pale, and cold sweat appears. It does not improve with rest.

5-year survival rate
Stage I: 87.8
Stage II: 62.0
Stage III: 40.5
Stage IV: 7.2

High blood pressure

Headache (pain from back of head to shoulder)
Shoulder stiffness
Numbness in the hands and feet

If left untreated…
1. hypertensive encephalopathy
Significant hypertension causes cerebral edema and loss of brain function. 2.

2. cerebral hemorrhage
Cerebral hemorrhage occurs when cerebral blood vessels break due to high blood pressure. 3.

3. subarachnoid hemorrhage
Hypertension causes aneurysms in cerebral blood vessels, which rupture, resulting in subarachnoid hemorrhage. 4.

4) Cardiac hypertrophy and heart failure
If hypertension continues for a long period of time, cardiomegaly will occur and eventually heart failure will occur. Ischemic heart disease is also more likely to occur.
Ischemic heart disease is also more likely to occur.

5. nephrosclerosis
Continued high blood pressure causes small blood vessels in the kidneys to harden, eventually leading to kidney failure.

6. aortic dissection
Aortic dissection occurs when the wall of a blood vessel tears due to high blood pressure, allowing blood to enter the wall. It is a disease with a high mortality rate. 7.

7. cerebral infarction (lacunar)
Small arteries in the brain become blocked in several places. In case of atherosclerosis, large blood vessels are blocked.

If you have any symptoms at all, it is advisable to measure your blood pressure.

Large amount and frequency of urination.
Sudden weight loss.
Sluggishness and tiredness in the whole body.
Blurred vision (vision impairment).
Sugar in the urine.
Numbness in hands and feet
Impotence (loss of libido)
Abnormal menstruation

Diabetic retinopathy, diabetic neuropathy, and diabetic nephropathy are called the three major complications. These complications are unique to diabetes, and if blood sugar is not controlled, these complications will appear within 10 to 15 years from the onset of diabetes.

《Diabetic Retinopathy》
Diabetic retinopathy is a condition in which the blood vessels in the retina at the bottom of the eye deteriorate, weakening vision and, in some cases, causing blindness.

《Diabetic neuropathy》
Diabetic neuropathy is one of the earliest complications to appear. The symptoms of peripheral neuropathy in the feet and hands vary widely, and you may not even notice numbness in your hands and feet, or pain from injuries or burns. In addition, a variety of autonomic neuropathy symptoms may also appear, including muscle atrophy, muscle weakness, gastrointestinal problems, dizziness, abnormal sweating, impotence, and ED.

《Diabetic Nephropathy》
In diabetic nephropathy, the capillaries in the glomeruli of the kidneys, which produce urine, deteriorate and gradually become unable to produce urine. This leads to the need for dialysis (the production of urine by filtering out unwanted components of the blood using a machine). The patient will have to undergo dialysis at a hospital two to three times a week, which will have a great impact on their daily life. Currently, diabetic nephropathy is the number one cause of dialysis.

Atherosclerosis is a condition in which cholesterol and neutral fat accumulate in the arteries, causing them to become clogged or hardened and lose their elasticity and flexibility.
When arteries are elastic and flexible, they can supply the necessary oxygen and nutrients to organs such as the heart and brain, as well as muscles and other tissues. However, if blood lipids such as cholesterol accumulate in the arteries, if oxygen and nutrients are insufficient, or if the arteries are constantly stressed due to high blood pressure, the arteries will lose their elasticity and become stiff and brittle. This condition is called arteriosclerosis.

Atherosclerosis does not have subjective symptoms that clearly identify it as arteriosclerosis, making it difficult to detect arteriosclerosis early based on symptoms alone.

Risk factors
High blood pressure
Lack of exercise
Unbalanced diet

excessive fat in blood

Hyperlipidemia is a condition in which the amount of cholesterol and triglycerides in the blood is increased. Cholesterol is used to make hormones and cell membranes, and helps in the absorption of fats, while triglycerides are used as a source of energy, but excessive amounts of cholesterol can cause damage to the body. As with diabetes, there are few subjective symptoms, but arteriosclerosis can lead to serious diseases. It is said that there are currently about 7 million people suffering from this disease, and the number is on the rise.

Risk factors
(Excessive intake of cholesterol in the case of cholesterol, and overall overeating in the case of triglycerides)
Drinking too much alcohol (triglycerides)
Lack of exercise
Genetic predisposition, such as a family history of the disease

Fou infarction, Fou hemorrhage

Deficient blood heart disease (narrow heart disease, cardiac infarction)

Renal sclerosis, renal insufficiency

Large artery aneurysm (rupture), occlusive arteriosclerosis

Learn more about dyslipidemia (hyperlipidemia)

No Vein

Arrhythmia is a condition in which the pulse beats erratically. In many cases, patients first become aware of arrhythmia when they experience palpitations, or when they take their pulse and find that it is abnormally slow, too fast, skipping, or irregular.

Shortness of breath

In case of tachycardia/extrasystole
Sudden pounding in the chest
Jumpy pulse
Pain in the chest
Tightness in the chest

Even people who are not particularly ill may experience arrhythmia several times within the day. Some arrhythmias are nothing to worry about, and some are life threatening. Those that cause sudden collapse and fainting, or sudden onset of violent palpitations, require attention.

cerebrovascular disease

Diseases caused by abnormal blood vessels in the brain are called “strokes,” and cerebral infarction is one type of stroke. Other types of strokes include cerebral hemorrhage, in which a blood vessel breaks, and subarachnoid hemorrhage, in which a bump on a blood vessel bursts.

cerebral infarction

A cerebral infarction is a disease in which blood vessels in the brain become clogged and blood flow is stopped. It occurs when blood vessels in the brain are clogged by a blood clot and the blood viscosity increases. When blood stops flowing to the blood vessels of the brain, the brain tissue becomes necrotic or nearly necrotic due to lack of oxygen and nutrients.

Initial symptoms
When the onset of the disease is imminent, symptoms such as facial paralysis, speech disorder, and sensory disturbance appear.

・Paralysis of the face and limbs, and the inability to move only one side of the body.
・Inability to speak properly due to loss of speech
・Inability to close mouth and drooling
・Dizziness or lightheadedness
・Dizziness and dizziness
・Stumbling when no obstacles are in the way.

These symptoms are called TIA (transient ischemic attack) and disappear in a short period of time (usually 2 to 30 minutes). If left untreated, 4-20% of people will have a stroke within 3 months, and half of these will be within 48 hours.

If you are experiencing any of these symptoms, we recommend that you get checked out as soon as possible.

cerebral hemorrhage

An attack of cerebral hemorrhage occurs suddenly. Unfortunately, there are few symptoms that can precede it. In rare cases, symptoms similar to those of a TIA (transient ischemic attack) may occur. However, it is clear that the most common cause of cerebral hemorrhage is high blood pressure. The higher the blood pressure in a person, the less the blood vessels in the brain can withstand the high pressure, leading to the formation of small aneurysms.

If you have been diagnosed with high blood pressure on a regular basis, try to control your blood pressure and be prepared to see a doctor immediately if you have any symptoms of concern.
Be prepared to see a doctor as soon as you notice any symptoms that concern you.

subarachnoid hemorrhage

Subarachnoid hemorrhage is a horrible disease in which a blood vessel ruptures in the brain, causing blood to flow out, and if it occurs, there is a 30-50% chance that the patient will die. In addition, once it occurs, there is a possibility of recurrence and serious aftereffects such as movement disorders, speech and swallowing disorders, and mental changes may remain.

Therefore, it is best if you can recognize the signs of subarachnoid hemorrhage in advance and stop it from happening.

Disturbed blood pressure
A headache unlike any other
Dizziness or nausea
Symptoms such as eye pain or double vision

Risk factors
High blood pressure
Smoking habit

If you experience any of these signs, it is important to have an early examination.


All diseases that cause inflammation in the lungs are collectively called pneumonia. Pneumonia is a disease in which the lungs are attacked by pathogenic microorganisms, mainly bacteria and viruses. There are two types of pneumonia: infectious pneumonia such as bacterial pneumonia, viral pneumonia, and fungal pneumonia, which is caused by inhaling an infectious source, and non-infectious pneumonia such as drug-induced pneumonia and allergic pneumonia. The majority of pneumonia is the former, infectious pneumonia. Bacteria and viruses enter the body through the nose and mouth when we breathe, and healthy people eliminate these pathogens with their throats. However, if you have a cold and your throat is inflamed, the germs can pass through and enter your lungs, causing inflammation.

The pathogenic microorganisms that cause pneumonia (infectious) are mainly divided into the following four types
1. Bacteria (so-called “bacteria”)
  Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae (different from influenza virus), etc.

2. Viruses
Influenza virus, adenovirus, measles virus, cytomegalovirus, etc.
virus, etc.

Mycoplasma (an organism somewhere between bacteria and viruses)
4、Fungus (mold)

Since it is a lung disease or inflammation of the lungs, respiratory symptoms are the main ones. In other words, cough, phlegm, wheezing, etc. In addition, as a systemic reaction to the inflammation, the patient may develop fever, lose appetite, and become dehydrated due to lack of water intake. In severe cases of pneumonia, the patient may have difficulty breathing and may require a ventilator.

Pneumonia is the leading cause of death among Japanese people, mainly due to “aspiration pneumonia” in the elderly, but even if you are young, it is important to treat it as early as possible and not dismiss it as “just a cold. It is also important to get a flu shot in the winter.

major disease

Now, I would like to describe the ranking of diseases with a large number of patients in Japan.

No.1: Hypertension disease
No.2: Tooth related diseases
No.3: Diabetes mellitus
No.4: Cerebrovascular disease
No.5: Cataract
No.6: Malignant neoplasm (cancer)
No.7: Ischemic heart disease
No.8: Gastric ulcer and duodenal ulcer
No.9: Schizophrenia, schizotypal disorder, and delusional disorder
No.10: Viral hepatitis

Since we do not provide dental care, we would like to describe other highly ranked diseases that are not mentioned in this document.


A cataract is a disease in which the lens becomes cloudy and white with age, causing vision loss.

There are no symptoms in the early stages.
As it progresses
Blurred vision
Blurred vision
Double or triple vision
Feeling blurred by light
Feeling very blurry outdoors on a sunny day
I feel glare from the lights of oncoming cars.
Difficulty seeing far away, which makes me feel as if I am nearsighted

Cataract is a disease that can be cured by surgery.
Early detection and treatment of these symptoms is highly recommended.

Gastric ulcers and duodenal ulcers

The term “peptic ulcer” is used to refer to ulcers that form under the influence of stomach acid. The most common types of peptic ulcers are gastric ulcers and duodenal ulcers.
Gastric ulcers are more common in people after the age of 40, while duodenal ulcers are more common in young people in their teens and twenties.

Abdominal pain in the area of the midsection
Nausea, vomiting, loss of appetite, weight loss
Pain in the back
Bad breath, sour burps, heartburn

Risk factors
Physical and mental stress from irritability, overwork, lack of sleep, tension, anxiety, pre-surgery, etc.
Helicobacter pylori infection.
Excessive intake of hot or cold foods or spices
Taking strong or prolonged medication such as painkillers or steroids
Drinking alcohol
Irregular eating habits such as binge eating or eating too fast

The initial symptoms of stomach ulcers and duodenal ulcers are discomfort such as upset stomach and lethargy. These symptoms are common, but if these symptoms persist for a long time If these symptoms persist for a long time, it is best to see a doctor as soon as possible.

Schizophrenia, schizotypal disorder, and delusional disorder

Schizophrenia is a mental disorder characterized by the symptoms of hallucinations and delusions. Schizophrenia is characterized by symptoms such as hallucinations and delusions, as well as impairments in the ability to interact with people and live in the home and society (impairment of life), and difficulty in reflecting on the fact that one’s senses, thoughts, and actions are distorted due to the illness (impairment of awareness).
It is a very frightening disease that, like many other mental illnesses, can lead to a chronic course and the inability to lead a social or family life in some cases. It is also a major disease, affecting about 1 in 100 people.

The main symptoms are hallucinations, delusions, and loss of motivation.

Hallucinations are perceptions of things that are not actually there. It can be divided into auditory hallucinations and visual hallucinations according to the content of the perception. For example, a person may complain of “hearing voices” (auditory hallucination) or “seeing things” (visual hallucination).

Delusion is the conviction that something that is not true is true. Even if those around them try to persuade them that this is not true, they cannot correct it. Depending on the content of the delusion, it may be called paranoid delusion (a paranoid conviction that something unrelated is related to oneself. For example, “the person who coughed was just trying to hurt me”), paranoid delusions (e.g., “someone is watching my house”), delusions of poisoning (e.g., “my food is poisoned”), delusions of lineage (e.g., “I am a descendant of the emperor”), and delusions of grandeur (e.g., “I have invented something amazing”). I am a descendant of the emperor.

・Decreased motivation
Schizophrenia is characterized by a gradual loss of motivation. It is seen in many patients to varying degrees.

Lack of interaction with others. This is characterized by a lack of social interaction with others, avoidance of friends, and a tendency to stay at home.

・Dullness of emotions
The rich emotions of joy, anger, sorrow, and pleasure are reduced. The person may not find TV interesting, may not be able to smile, or may be unconcerned even when sad.

・Disorders of the thought process
You can tell by the way the patient talks. One of the most common disorders is “thought laxity”. The patient’s speech may gradually drift off to other topics or suddenly start talking about something else. In severe cases, the person may have “disorganized thinking,” in which others cannot understand the meaning of the conversation at all.

・Physical symptoms
Insomnia is common. It is important to note that insomnia is often the first symptom of the disease, or the first symptom of a recurrence. In some cases, the patient may complain of physical complaints such as palpitations, headache, and fatigue, even though there is nothing physically wrong with the body.

・Symptoms that appear on the face
Murmuring to oneself or laughing at something that is not funny. A frowning face or furrowed brow may also be seen. Emotional dullness: The face becomes less expressive due to emotional dullness.
Emotional dullness, resulting in a lack of facial expression.

If you have any of these symptoms, we recommend that you see a doctor as soon as possible.

viral hepatitis

Hepatitis is a condition in which inflammation occurs in the liver cells and hepatocytes are destroyed. Hepatitis can be caused by viruses, alcohol, autoimmunity, etc. In Japan, hepatitis caused by hepatitis B virus or hepatitis C virus infection accounts for the majority of cases. It is estimated that 1.3 to 1.5 million Japanese are infected with hepatitis B and 1.5 to 2 million with hepatitis C. Hepatitis B is the most common hepatitis in Thailand.
Hepatitis B is also common in Thailand and requires attention.

Hepatitis B
It can lead to fatal fulminant hepatitis.

Hepatitis C
Hepatitis C is known to cause cirrhosis and hepatocellular carcinoma in a high percentage of patients after 20 to 30 years if it becomes chronic.

Sexual contact is the most common cause.
In addition to this, medical treatment using instruments that have not been sufficiently disinfected
Tattooing and piercing
Sharing of razors and toothbrushes
Passing around syringes when using narcotics or methamphetamines, with the blood of a persistently infected person still attached to the syringe and used by the next person.

Generalized lethargy
Decreased appetite
Rash on the skin of the face and hands
Joint pain
Muscle pain

The Ministry of Health, Labor and Welfare (MHLW) launched the “Emergency Comprehensive Measures for Hepatitis C, etc.” in 2002. The Ministry of Health, Labor and Welfare (MHLW) launched the “Emergency Comprehensive Measures for Hepatitis C, etc.” in 2002 and recommends that all citizens undergo hepatitis virus testing at least once. In particular, people over 40 years old are recommended to be tested for viral hepatitis at least once.

Vaccination against hepatitis B is also recommended as a vaccine exists. Thailand is an area where the hepatitis B virus is very prevalent. Protect yourself with a vaccine.

Other Diseases

Here is a list of other major diseases that need attention.


Depression is a chronic condition that causes psychological symptoms such as depressed mood and loss of motivation (appetite, desire to sleep, sexual desire, etc.) as well as various physical symptoms.
In severe cases, it is a very scary disease that makes it almost impossible to continue social and family activities, and many people end up committing suicide.

High number of patients
It is said that 1 in 15 people will suffer from depression in their lifetime.
There are more than one million depressed patients in Japan who seek medical care.
There are more than 75% of depressed patients who do not seek medical care despite their depression.

Trouble sleeping
Feeling depressed
Feeling sad
Somewhat hopeless
Decreased ability to think
Decreased concentration and work efficiency
Inability to make minor decisions
Difficulty paying attention and understanding what others are saying
Unable to motivate yourself to do the things and hobbies you used to love
I have trouble talking to my friends and family, and I find it boring.
Not interested in watching TV or reading newspapers.
Not interested in grooming or fashion.
Cannot sit still due to anxiety.
I don’t feel the energy in my life every day.
Waking up earlier than the alarm in the morning
Waking up many times during the night
Feeling like you have not slept even though you have slept well
Decreased (and sometimes increased) appetite
I can’t taste anything I eat, and I can’t eat enough
Weight loss of several kilograms in one month, even though you are not dieting
Fatigue, tiredness
I feel tired and lazy.
I feel tired all the time.
Irregular menstruation

Decreased libido
Headache (dull, unrefreshing pain like a pot on the head)
Feeling of heaviness in the head
Pain in various parts of the body such as shoulders, back, and extremity joints
Heart pounding
Stomach pain
Sweating breath
Choking sensation

Just like any other illness, depression will gradually worsen if it is left untreated.
Therefore, it is important to recognize depression while the symptoms are mild and start treatment.
If you experience any of the above symptoms, it is recommended that you get checked out before it becomes a serious condition.


It is estimated that about one in three Japanese suffer from chronic headaches, or “headache sufferers”. There are various types of chronic headaches, but the most common type is tension-type headache, which accounts for 22.3% of Japanese people over the age of 15. The next most common type is migraine (8.4%), and a more rare type is cluster headache. Headaches are very difficult to diagnose, and it is highly necessary to have a specialist make a thorough diagnosis.

《Tension-type headache》
Tension headaches are lighter than migraine headaches, and the pain feels like the entire head is being weighed down or squeezed. Tension-type headaches, which are caused by stiff muscles, are more common among people who work at a desk, bend over for a long time, or look at a computer screen for a long time. It can also be caused by wearing ill-fitting glasses or other eye strain. Tension headaches from the mind are more common in people who are vulnerable to mental stress, such as relationships at work or family problems. The headache starts with a vague feeling of dullness in the head and tends to last throughout the day.

Women are 3.6 times more likely to suffer from migraine than men. Women are 3.6 times more likely to suffer from migraine than men, with about 20% of women in their 30s suffering from migraine. Symptoms include a throbbing, pulsating pain that occurs on one side of the head, sometimes both sides. The cause of the pain is thought to be neurogenic inflammation around the blood vessels or abnormal dilatation of the blood vessels. It occurs about once or twice a month, and the pain lasts from a few hours to three days in some people. It is also accompanied by nausea, glare from light and sensitivity to sound. Some migraine sufferers say that they know a headache is coming when they start to yawn, feel hungry or irritable. Some people also experience flashing lights in front of their eyes and blurred vision as an aura of headache. In addition, some people experience paralysis of the limbs.

Headaches that require attention
If you have a headache that you have never experienced before, such as a sudden intense pain or a headache that gradually builds up, or a headache that is accompanied by numbness in the limbs, slurred speech, or fever, you should immediately go to the emergency room and see a neurosurgeon.

・Subarachnoid hemorrhage is characterized by a sudden rupture of an artery in the brain, causing blood to accumulate under the arachnoid covering the brain, resulting in a sudden, cracking headache. The most common symptoms are nausea, vomiting, loss of consciousness, etc. It is more common in people in their 40s or older, and an aura of light-headedness may occur a few days to a few weeks before the attack.

・Cerebral hemorrhage – often caused by a rupture of a blood vessel in the brain due to high blood pressure, resulting in a sudden headache that peaks within a short period of time. Even if the headache is mild, it may be accompanied by paralysis of limbs, slurred speech, nausea and dizziness.

・Brain tumor – As the tumor grows in the brain, the pain becomes more and more severe.
Depending on the location of the tumor, it may cause paralysis of the limbs and vision problems.

・Meningitis/encephalitis – A viral or bacterial infection of the meninges can cause a high fever and a severe headache. It is also characterized by stiffness in the back of the neck. If the inflammation reaches the brain, encephalitis occurs, causing paralysis and loss of consciousness.

・Chronic subdural hematoma – A head injury (or minor shock) causes gradual bleeding between the dura and arachnoid membranes under the skull, and after a month or two, the hematoma presses on the brain, causing a headache. It is especially prone to elderly people, and can be mistaken for dementia, as it can cause fogginess, forgetfulness, and urinary incontinence. If the hematoma is removed, the symptoms disappear.

There are some headaches that can be life-threatening, so don’t simply assume that you have a tension headache.
